Abstract

Hydridosilicate anions (ArSiH(4) and SiH(6)) were stabilized as ligands in diruthenium Si-H σ-complexes [{(PhBP(Ph(3))Ru}(2)(μ-Cl)(μ-η(3),η(3)-H(4)SiAr)] (Ar = 2-MeOC(6)H(4), Mes, Ph) and [{(PhBP(Ph)(3))Ru}(2)(μ-η(4),η(4)-H(6)Si)] (see picture). These complexes were formed under mild conditions and characterized by single-crystal X-ray diffraction (see picture), NMR and IR spectroscopy, and computational techniques.

摘要

杂化硅阴离子(ArSiH(4)和SiH(6))作为配体稳定在二钌 Si-H σ-配合物 [{(PhBP(Ph(3))Ru}(2)(μ-Cl)(μ-η(3),η(3)-H(4)SiAr)] (Ar = 2-MeOC(6)H(4), Mes, Ph) 和 [{(PhBP(Ph)(3))Ru}(2)(μ-η(4),η(4)-H(6)Si)] 中(见图片)。这些配合物是在温和条件下形成的，并通过单晶 X 射线衍射(见图片)、NMR 和 IR 光谱以及计算技术进行了表征。
